IMPROVEMENT IN PAPER'FASTENINGS.

Specification forming part of Letters Patent No. 89,898, dated May 11, 1869.

To all whom it may concern Be it known that I, J. F. TAPLEY, of Spring. iield, in the county of Hampden, and State of Massachusetts, have invented a new and ,Improved Method of Fastening the Leaves of Monthly Calendars, or other sheets designed to be torn from the binding; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

'lhe nature of my invention consists in using a metal plate, the edge of which has sections cut out, leaving projections or teeth, which, being bent at right angles with the plate, pierce the sheets, and, being clinched on the opposite side, hold them irmly together.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction.

Figure 3 in the accompanying drawings represents the manner of cutting the metal for use. The projections a a a a a represent the `teeth designed to pass through the sheets,

those marked b b being designed to bendback round theedges of the sheets, for the purpose of holding them compactly together and to l give a better nish to the whole.

Fig. 4 represents the teeth and side projections as they appear bent down or clinched onto the sheets. Fig. 5 shows the sheets pierced for the teeth to go through; Fig. 1, the calendar orsheets complete, with the plate fastened on. Fig. 2 represents the plate fastened on, with a portion of the sheets torn oif; and Fig. 6, a sectional view. Y

When the sheets are too thick for the metal unaided to pierce th'em, they should be perforated in a suitable manner, as shown in Fig. 5. A large portion of the surface being cut across for the teeth to go through renders the tearing 0E of the sheets on a line'with the edge of the metal an easy matter, and leaves the edge of the stumps, after tearing, in a more finished condition than they would be wit-hout being' clamped down and partially cut.

Another advantagethis mode has is, that.

very thin metal can be used, thus lessening the expense; for itis evident that when clinched yon in the manner described very thin metal will present as firm an edge as a much heavier metal would if fastened on with pasted paper, g

or riveted in any other way. Then, by using thin metal, it can be embossed with a variety of figures, in the manner of ,brass mats for yphotograph-pictures, or with the name of the manufacturer, making a highly ornamental and very cheap head-piece, and doing away with the necessity of covering with a printed label.

I claim- Securing or binding sheets by a metal plate,
